Area under the receiver operator curve (AUC) and 95% bootstrap confidence intervals (CI) for the new prediction rule (RISSC85) alone, and with the inclusion of parameters
| AUC (95% CI) | |
|---|---|
| RISSC85 | 0.63 (0.61 to 0.67) |
| RISSC85 + CRP | 0.63 (0.61 to 0.67) |
| RISSC85 + BUN | 0.63 (0.61 to 0.67) |
| RISSC85 + X-ray | 0.63 (0.61 to 0.67) |
| RISSC85 + BAC | 0.64 (0.62 to 0.67) |
| RISSC85 + VIR | 0.64 (0.62 to 0.67) |
| RISSC85 + ETIO | 0.64 (0.62 to 0.68) |
| Simplified RISSC85 | 0.59 (0.57 to 0.62) |
BAC = bacterial agents. BUN = blood urea nitrogen. CRP = C-reactive protein. ETIO = aetiology. VIR = viral agents.
